Abstract
A device for actuating a system such as a clutch or a gearbox associated with an engine, particularly a motor vehicle engine, and comprising control element (26-31) and an actuation member (38). According to the invention, the device furthermore includes: a first shaft (4) rotationally driven by the engine; a second shaft (6) integral with the actuation member; coupling member (10, 13, 15, 16, 33) for coupling the second shaft to the first shaft under the action of the control element; a member (16, 32, 33; 48, 53) for uncoupling the second shaft from the first shaft after the second shaft has rotated through a predetermined angle; and a return spring (35) for returning the second shaft to its initial position after it has been uncoupled from the first shaft.

Device for actuating a clutch or a gearbox associated with an engine, said device comprising control means (26-31) and an actuation member (38), and furthermore including:
- a first shaft (4) adapted to be rotationally driven by the engine:
- a second shaft (6) integral with the actuation member;
- coupling means (10, 13, 15, 16, 33) for coupling the second shaft to the first shaft under the action of the control means;
- means (48, 53) for uncoupling the second shaft from the first shaft after the second shaft has rotated through a predetermined angle;
- and
- return means (35) for returning the second shaft to its initial position, prior to the rotation thereof, after it has been uncoupled from the first shaft;
- the improvement comprising automatic means (48, 53) for keeping the coupling means coupled for as long as the second shaft has not made a rotation through the predetermined angle.
