Abstract
An assembly for a drug delivery device comprises: a housing having a proximal end and a distal end, a dose setting and drive mechanism comprising a dose setting member moveable relative to the housing in a dose setting operation from an initial position to a dose set position, the dose setting and drive mechanism further comprising a piston rod displaceable in the distal direction relative to the housing in a dose delivery operation, wherein, during the dose delivery operation, the piston rod is displaced relative to the housing by a displacement distance which is determined by the set dose, a guide track, a tracking member configured to cooperate with the guide track, and a coupling mechanism configured to operatively couple the tracking member to the dose setting and drive mechanism, wherein the coupling mechanism has a coupled state and a non-coupled state.
