Zusammenfassung:	Invention regards an actuator assembly (1) comprising an actuator (3) with a cylinder-shaped shaft (5) rotatable around an axially extending center axis (A), said shaft (5) having an envelope surface (7). The assembly (1) further comprises a fixed, tubular bearing (9) surrounding a section of the shaft (5), said bearing (9) having an inner surface (11) facing the envelope surface (7) of the shaft (5) so that an interface (13) between the shaft (5) and the bearing (9) is created. The interface (13) comprises at least one circumferential groove (15) and at least one complimentary circumferential ridge (17). The groove (15) is arranged in the one of the envelope surface (7) of the shaft and the inner surface (11) of the bearing and the complimentary ridge (17) is arranged in the other of the envelope surface (7) of the shaft and the inner surface (11) of the bearing.
