1. A monitoring device for monitoring the injection of a medicine using an injection device, the monitoring device comprising:
- a sleeve configured to be removably mounted to an injection device, where the sleeve comprises;
an annular shape having an elongate slit used to removably mount the sleeve to the injection device; and
an elongate rail having a pen identifier,a housing comprising;
an optical motion detection system that passively detects both rotational and longitudinal continuous movement of a shaft of the injection device relative to a body housing of the injection device using an optical sensor as the shaft moves distally and axially outward from the body housing during dose setting and as the shaft moves proximally and axially back into the body housing during dose delivery when the housing and sleeve is attached to an outside surface of the body housing of the injection device, where the housing is rotationally and axially fixed relative to the body housing such that all components of motion detection system are contained within the housing and do not move relative to the body housing, where the optical sensor is positioned such that it projects over the shaft to track both the axial and rotational movement of the shaft in a proximal direction during injection of a set dose of medicine and in a distal direction during dose setting; and
a complimentary rail configured to removably engage with the elongate rail such that when engaged, the housing and the sleeve are securely attached and the pen identifier is in operative communication with the optical motion detection system,wherein the detection of the shaft movement does not involve mechanical movement of any part of the motion detection system.

19. A monitoring device for removable attachment to a pen type injection device, where the monitoring device comprises:
-
a housing comprising an optical motion detection system that passively detects both rotational and directional movement of a part of an injection device using an optical sensor when the housing is attached to an outside surface of a body housing of the injection device, where the housing is rotationally and axially fixed relative to the body housing such that all components of motion detection system are contained within the housing and do not move relative to the body housing, where the optical sensor is positioned such that it projects over the moving part of the injection device to track both the axial and rotational movement of the part in a proximal direction during injection of a set dose and the axial movement of part of the injection device in a distal direction relative to the body housing during dose setting; and a removable mounting device that releasably attaches to the body housing of the injection device and to the monitoring device housing, where the monitoring device housing further comprises a plurality sensor switches that engage projections on the mounting device when the monitoring device housing is attached to the mounting device, wherein the engagement of the sensor switches with the projections allows the pen type injection device to be identified.
