1. A device for actuating doors of a vehicle comprising:
an actuator element mounted within an actuation device for relative rotational movement with the actuator element about an axis M and reciprocal linear movement in a direction X wherein the direction X is parallel to the rotational axis M;
a shaft element extending along axis M and having a first end connected to a door and a second end connected to a front surface of the actuator element;
a drive means for sequentially driving one of (1) the actuator and (2) actuation device about axis M and thereafter in direction X through a stroke distance H between a first position and a second position;
the actuation device comprises a cylinder element having rotational symmetry around axis M and having a front surface in which a carrier element is rotatably mounted about axis M;
the carrier element has a coupling on a surface thereof which engages with a coupling on the front surface of the actuator element when the actuator element is in the first position;
and link means for linking an outer surface of the actuator element to an inner surface of the actuation device.
