Abstract: In one form, the invention relates to a door drive for a door, the door drive comprising: a drive motor, a drive shaft drivable and thereby rotatable by the drive motor, a clutch, and a threaded spindle which is drivable and thereby rotatable by the drive shaft via the clutch, wherein the clutch comprises: a catch element, an actuating element which, by rotating the drive shaft, is drivable and thereby rotatable around an actuation rotational axis by the drive shaft, the actuating element comprising at least one first actuation area, and a clutch element which comprises at least one second actuation area corresponding to the first actuation area, wherein the clutch element is translationally movable along the actuation rotational axis relative to the catch element between at least one decoupling position in which the clutch element is decoupled from the catch element, and at least one coupling position in which the clutch element is coupled to the catch element, and wherein a relative rotation between the actuating element and the clutch element, the relative rotation being effectable by rotating the drive shaft, can be converted, by means of the actuation areas, into a translational movement of the clutch element from the decoupling position into the coupling position, the translational movement taking place along the actuation rotational axis, relative to the catch element, relative to the actuating element and in the direction of the catch element.
