Actuator module for a transmission having at least two translation stages, comprising: - a transmission actuator which is configured to perform an actuating movement parallel to an actuating direction; - a detection means; and - a transmission mechanism, which is configured to convert the actuating movement into a shift movement which causes a shift position to be set in the transmission, wherein the transmission mechanism has a first coupling point via which it is connected to the transmission actuator and can receive its actuating movement, wherein the transmission mechanism has a second coupling point via which it can be connected to a shift element of a transmission in order to apply the shift movement to the shift element, wherein the transmission mechanism has a transmission element which is configured to convert the actuating movement into the shift movement, wherein the detection means is configured to detect the actuating movement and/or the shift movement and/or a movement of the transmission element, and wherein the transmission actuator can be actuated electrically, wherein the transmission element is provided to rotate about a rotation point between the coupling points (8a, 8b), and is configured to generate a shift movement by means of rotation when the actuating movement is applied, characterised in that the actuator module has a length compensation mechanism, which is configured to perform a length compensation between the coupling points (8a, 8b) when the actuating movement is applied, wherein the length compensation mechanism has an elastic prestress which acts between the coupling points (8a, 8b) and is orientated in such a way that it always acts in the direction of extension of the transmission element. - a transmission actuator which is configured to perform an actuating movement parallel to an actuating direction; - a detection means; and - a transmission mechanism, which is configured to convert the actuating movement into a shift movement which causes a shift position to be set in the transmission, wherein the transmission mechanism has a first coupling point via which it is connected to the transmission actuator and can receive its actuating movement, wherein the transmission mechanism has a second coupling point via which it can be connected to a shift element of a transmission in order to apply the shift movement to the shift element, wherein the transmission mechanism has a transmission element which is configured to convert the actuating movement into the shift movement, wherein the detection means is configured to detect the actuating movement and/or the shift movement and/or a movement of the transmission element, and wherein the transmission actuator can be actuated electrically, wherein the transmission element is provided to rotate about a rotation point between the coupling points (8a, 8b), and is configured to generate a shift movement by means of rotation when the actuating movement is applied, characterised in that the actuator module has a length compensation mechanism, which is configured to perform a length compensation between the coupling points (8a, 8b) when the actuating movement is applied, wherein the length compensation mechanism has an elastic prestress which acts between the coupling points (8a, 8b) and is orientated in such a way that it always acts in the direction of extension of the transmission element.
