Claim:
1. A torque detecting device adapted to be mounted to a torque transmitting device, the torque transmitting device including rotatable input and output shafts, said torque detecting device comprising: an input gear adapted to be sleeved on the input shaft; an output gear adapted to be sleeved on the output shaft; a planet gear unit including a first angle sensing unit including a first magnet disposed on said sun gear, and a first magnetic induction module disposed for sensing an angle by which said first magnet is rotated during rotation of said sun gear; and a calculating unit connected electrically to said first angle sensing unit, and disposed for calculating a torque of said input shaft relative to said output shaft with reference to the angle sensed by said first angle sensing unit.
