Abstract: A stator-housing unit for an electric machine includes a housing and a stator connected to the housing and bordering a bearing shield. A deviation in shape for increasing a coefficient of friction between the stator and the housing is realized on at least one subarea of a contact area between the stator and the housing, with the subarea being realized at one end of the stator.

Abstract: An actuator (10) includes sensors (12) which are used to detect variables representing the operating state of the actuator (10) and are connected to an evaluation unit (16) associated with the actuator (10). The evaluation unit (16) is connected to sensors (12) and/or control actuating elements (13) by means of a first data bus (15). The sensors (12) are used to detect measurable variables representing the operating state of the actuator (10), and to transmit the same to the evaluation unit (16).

Abstract: The invention relates to a shaft coupling for connecting a transmitter (15) to an electrical machine, in particular to an electric motor (16), wherein an end section (5) of a transmitter shaft (6) and an end section (2) of a motor shaft (1) are arranged facing each other, and at least one torque transmission element (9) is arranged between the end sections (5) of the transmitted shaft (6) and the motor shaft (1). The torque transmission element (9) has on each of the front faces thereof a transverse groove (10,11) passing through the center thereof, wherein claw-like elements (3, 4, 7, 8) of the end sections (2, 5) of the motor shaft (1) and the transmitter shaft (6) correspond in the assembled state with the transverse grooves (10,11) of the torque transmission element (9) in such a way that a torque transmission takes place from the motor shaft (1) to the transmitter (15), which compensates both radial and axial offsets as well as angular offsets of the motor and the transmitter shaft.
