A torque sensing system (31) is disclosed as including a stationary part (50) with an electricity transmitting copper coil (62), and a rotating part (10) rotatable relative to the stationary part about an axis of rotation (C-C, D-D, F-F), and having a body (12) fixedly engageable with a vehicle spindle (33) for receiving torque input from the vehicle spindle and simultaneous rotation about the axis of rotation, an outer circumferential surface (43) for engagement with and transmitting said torque input to a one-way sprag clutch (35), four strain gauges (40a, 40b, 40c, 40d) fixedly engaged with the body for sensing torque applied on the body and outputting torque-related signals representing the magnitude of the torque applied on the body, an electricity receiving copper coil (24) for wirelessly receiving electricity transmitted by the electricity transmitting copper coil of the stationary part, and a printed circuit board (16) having a first major surface (17) which is substantially perpendicular to the axis of rotation.
