<p>An actuation device (10) comprises a driving member (30), a driven member (40) and an actuator device. The driven member (40) has a seat (44), in which there is operatively inserted, with possibility of relative movement, an engagement part (35) of the driving member (30). According to the invention also the driving member (30) has a seat (34), which, in at least one position of the actuation system, at least partially faces the seat (44) of the driven member (40). The actuation system further comprises a floating body (50), displaceable in a controlled way between the two seats (44, 34) when said seats at least partially face one another.</p> |
