1. An assembly comprising:

  • a drug delivery device (1) comprising;

    a reservoir (5) for a drug,an outlet (6) for the drug,a drug expelling mechanism for expelling the drug from the reservoir and out through the outlet,a housing (3) in which at least a portion of the drug expelling mechanism is arranged, anda first coupling structure (14) for a cap, the cap (20) adapted to cover the outlet, comprising;

    a second coupling structure for engaging the first coupling structure, and a monitoring device (30) comprising;

    a housing portion (31),a structure for detecting or registering an action performed in the drug delivery device, anda third coupling structure (32 or 52) adapted to engage the first coupling structure on the drug delivery device,whereby the monitoring device is arranged in a pre-determined mounted position relative to the drug delivery device when the first and third coupling structure engage each other, thus allowing information to be transferred between the drug delivery device and the monitoring device, andwhereby the monitoring device does not cover the outlet when arranged in the mounted position, thus allowing an amount of drug to be expelled from the reservoir while the monitoring device is coupled to the drug delivery device.
