A torque detecting device is adapted to be mounted to a torque transmitting device. The torque transmitting device includes rotatable input and output shafts. The torque detecting device includes input and output gears for being sleeved respectively on the input and output shafts and a planet gear unit that includes a ring gear meshing with the input gear, a sun gear disposed in the ring gear, a carrier gear meshing with the output gear, and a plurality of planet gears. The planet gears are coupled rotatably to the carrier gear, are disposed between the sun and ring gears, and mesh with the ring and sun gears such that, when the input gear is rotated relative to the output gear by an angle, the sun gear is driven to rotate reversely by a larger angle.
