摘要

The adjuster (1) has an actuator (3) actuating a hydraulic valve and fastened to a housing element (5) by a fastener (4). The fastener is formed as a screw-free fastening element and a bayonet joint. The bayonet joint comprises two radially outwardly extending projection parts that are arranged under associated hook-shaped holders formed at the housing element. A spring element is arranged between the projection parts and the hook-shaped holders, and produces spring force in direction of an axle (8) of the actuator.
