The present invention relates to a drug delivery device for selecting and dispensing a plurality of user-variable doses of a medicament comprising a dose limiter for preventing the set dose from exceeding the amount of liquid remaining in a cartridge of the drug delivery device. The device comprises: a housing (10, 20), a dose selector (140) for selecting a dose by rotation relative to the housing (10, 20), a dosing element (40, 130), and a releasable clutch (45 , 143), the releasable clutch (45, 143) is used to couple the dose selector (140) to the dosing element (40, 130) in rotation during dose selection and to make the dosing element (40, 130) are rotationally disengaged from the dose selector (140). The clutch includes a male spline (45), a corresponding female spline (143), and is oriented such that re-engaging the clutch will direct the male spline (45) to a predetermined rotation relative to the female spline (143) Orientation of curved or sloped surfaces (142).
