A clutch actuator for a door lock comprises a first shaft with a longitudinal shaft axis and an azimuthal bearing surface, wherein the azimuthal bearing surface provides a first block against a rotation in a first direction, the first direction is an azimuthal direction and the first block extends in at least one second direction, the first and the second direction are linearly independent. The clutch actuator further comprises a coupling member, being movably supported relative to the shaft by the bearing surface between an open position and a closed position, wherein the coupling member has at least a first spring block and a second spring block and wherein the first spring block and the second spring blocks face in mutually opposite directions, said mutual opposite directions being parallel to a third direction. A helical spring is movably supported relative to the first shaft to enable a movement parallel to the third direction, wherein the movement parallel to the third direction is limited in the third direction by the first spring block and in the opposite direction by the second spring block and wherein the helical spring has multiple windings. A spindle is torque proof connected to a motor shaft and rotatably supported relative to the first shaft, wherein a protrusion of the spindle engages in a void between two adjacent windings of the helical spring. Safety provided by the clutch actuator against manipulation is enhanced if the coupling member has a first interlocking protrusion extending towards the spindle and if the spindle has a second interlocking protrusion extending towards the coupling member, wherein in the open position of the coupling member the second interlocking protrusion intersects the path of the first interlocking member form the open position to the closed position.
