1. A torque measurement system for measuring a torque acting on a rotatable shaft that is configured to rotate about an axis upon receipt of an input, the torque measurement system comprising:

  • a first housing portion having a first end adapted to be fixedly coupled to the rotatable shaft and a second end, the first housing portion adapted to be positioned coaxial with the rotatable shaft;

    a second housing portion having a first end spaced apart from the second end of the first housing portion so as to define a gap between the first housing portion and the second housing portion, the second housing portion adapted to be fixedly coupled to the rotatable shaft;

    a sprocket coupled to the second end of the first housing portion, wherein the first housing portion is configured to transmit a torque applied to the rotatable shaft to the sprocket;

    at least one dedicated elastically deformable mechanical element embedded on the rotatable shaft, the first housing portion, or both, wherein a second end of the first housing portion is configured to be displaced relative to the first end upon transmission of the torque from the rotatable shaft to the sprocket; and

    at least one sensor that observes at least one of the second end of the first housing portion, the first end of the second housing portion and the gap and generates sensor signals based on the observation, the sensor signals indicative of a torque acting on the rotatable shaft, the sensor adapted to be fixedly coupled to a static frame.
