Adjustment device for linearly moving a driven element

An adjustment device which comprises a stator, a driven element, a guide device which, in the operational state of the adjustment device, provides a guided support of the driven element with respect to the stator in a drive direction, a rotor which executes a rotation or a rotation as an adjustment movement, a support device which movably supports the rotor relative to the stator along the drive direction, a drive device comprising a coupling device and a clamping device;

• wherein the coupling device comprises a connection device which is fastened to the driven element or the rotor;
• wherein, in a release state, the clamping device permits a movement clearance between a connection section of the connection device and either the rotor or the driven element in order to establish a mounting state of the adjustment device and wherein, in a clamping state, the clamping device rigidly couples the connection section and either the rotor or the driven element in the drive direction, thereby causing a rotational relative movement about a rotational axis, which runs along the drive direction, between the driven element and the rotor.
