Abstract

A camshaft adjustment device comprising an electromagnetic actuator (3) having an armature that can be adjusted axially along an adjustment axis (5) for actuating a hydraulic valve for camshaft adjustment, and fastening means for fastening the actuator (3) on an engine element (3), wherein the fastening means comprise spring means (12), which tension the actuator (3) against the engine element (2) in a securing position (13), wherein the fastening means have positive-fitting means (8) as an anti-twist device for preventing a twisting movement of the actuator (3) in an installation position (7) relatively to the engine element (2), which are constructed and arranged in such a manner that the actuator (3) can be moved to the engine element (2) by means of a pure translational installation movement and wherein the spring means (12) in the securing position (13) bar a de-installation path for a purely translational de-installation movement of the actuator (3) opposite to the installation movement in such a manner that the same cannot be de-installed oppositely to the purely translational installation direction.
