1. An actuating device (10) for an automated manual transmission (12) of a motor vehicle, wherein a selector element or shift element of the automated manual transmission is movable by the actuating device (10) for setting a shift gate or for engaging or disengaging a gear, the actuating device (10) comprising:
a housing (18) having a cylindrical receiving chamber (50),
a pressure-medium-operated actuator (54) having a piston (58) and a piston rod (64),
wherein the piston rod (64) is connectable to the selector element or shift element of the manual transmission,
wherein the piston (58) is arranged in a radially sealed manner in the receiving chamber (50) of the housing (18) of the actuating device (10) and is coaxially movable in the receiving chamber (50),
a sensor system (30) including a magnet (38) and a magnetic-field-sensitive sensor (32),
wherein the magnet (38) is arranged on an end face of the piston (58) remote from the piston rod (64) by a holding device (44),
wherein the sensor (32) is arranged radially with respect to the magnet (38) on the housing,
wherein the holding device (44) is connected to the piston (58) such that the piston is rotatable about a longitudinal central axis (52) of the receiving chamber (50),
wherein the holding device (44) has a hollow cylindrical or a hollow-cylinder-segment-shaped geometry,
wherein a rod-shaped or plate-shaped anti-rotation element (80) having two ends is form-lockingly accommodated at least with the two ends in an associated recess (120) in the housing (18), and
wherein the anti-rotation element (80) extends across the holding device (44) in the manner of a secant with play and spaced apart from the magnet (38), wherein the piston (58) is moveable axially and rotationally, wherein a rotational movement of the holding device (44) about the longitudinal central axis (52) of the receiving chamber (50) is prevented.
