This device comprises an output wheel (17), an elastically deformable element placed in between this wheel (17) and an output shaft (31) carrying an output wheel (28). A system of speed-increasing/reversing pinions (47, 52, 53) meshes with the output wheel (28) and drives in rotation an electric collector (32, 33) which interacts with conductive tracks (35, 39) carried by gearwheels (35, 38) driven by the output wheels (17) of the reduction gear and (28) of the damper, these tracks being connected to an electronic circuit enabling the torque to be measured upon each revolution of the collector (32). This torque sensor enables an abnormal torque of the part driven by the output shaft to be detected, and an order to be given, for example, immediately stopping the motor if a critical value of the torque is detected. <IMAGE> |
