A motor (3) is driven by the control block (6) and is connectable to the clutch (2) pedal. The control block enables to come via the pedal to the coupling point at a first speed and then allows it to come into shock-free engagement at a speed lower than the first. A supplementary hydraulic system (3,4,11) is provided between the control block and the motor. In the control block is a transmission for pressure in the hydraulic system of the vehicle to the supplementary hydraulic system. The supplementary hydraulic system is virtually pressure-less in the rest state of the control. The motor (3) in reaction to the pressure of the hydraulic system when the operating device (9) comes into effect is directly driven via the supplementary hydraulic system.
