According to the invention, the first end ( 2 a) and the second end ( 2 b) of the pre-tensioned spring ( 2 ) are positioned in their pre-tensioned states against a first stop ( 1 a) and a second stop respectively ( 1 b). The rotating body ( 1 ) is first rotated at least X times about its longitudinal axis, without the action of external forces, whereby the first end ( 2 a) engages once in a cam wheel ( 3 ) during each rotation, said wheel having at least X+ 1 teeth ( 3 b) and at least one cam ( 3 a) that runs parallel with the teeth ( 3 b). The cam wheel ( 3 ) thus rotates one tooth ( 3 b) further with each rotation of the rotating body ( 1 ). After at least X continuous rotations, the rotating body ( 1 ) is subsequently subjected to pre-tensioning until the cam wheel ( 3 ) and its cam ( 3 a) lies against a third stop ( 6 ) and the first end ( 2 a) simultaneously engages in the cam wheel ( 3 ). The rotation is then continued in order to increase the torque, whereby the first end ( 2 a) remains engaged in the cam wheel ( 3 ) and is released from its position against the first stop ( 1 a). The invention also relates to the use of said method in an actuating drive for setting the valve stroke of a motor vehicle.
