The device (4) comprises a drive member (1) for driving a piston rod (5) and a dose member (46) for actuating the drive member (1). The piston rod (5) is coupled to the drive member (1) such that a relative translational movement of the drive member (1) and the piston rod (5) is allowed and a relative rotational movement is prevented. The drive member (1) is configured to be driven by the dose member (46) around the longitudinal axis in a first (110) and a second rotational direction (111) opposite to each other. Furthermore, a drug delivery device (4) is provided, wherein the drive member (1) has stable and unstable states and wherein in an unstable state the drive member (1) is biased by biasing means (3) towards a stable state.
