The device (1) comprises: a rotary drive motor (2), a speed reducer (4) of epicyclic type including an input shaft (3), and output shaft (9) and a rotatable outer body (10) coaxial with the input and output shafts (3, 9) and with which is associated a resilient biasing member (16) operable to oppose its rotation; the input shaft (3) being coupled for rotation to the motor output shaft (2) and having an output shaft (9) coupled operatively to a load; an electric transducer (21; 26, 27) operable to provide signals indicative of the magnitude of the load applied to the output shaft (9) of the speed reducer (4); and a control and command unit (ECU) arranged to pilot the motor (2) in a predetermined manner. <IMAGE> |
