Abstract
A drug delivery device for selecting and dispensing a number of user variable doses of a medicament includes a dose limiter for preventing the setting of a dose exceeding an amount of liquid left in a cartridge of the drug delivery device. The device includes a housing, a dose selector for selecting a dose by rotation relative to the housing, a dosing element, and a releasable clutch for rotationally coupling the dosing element to the dose selector during dose selecting and for rotationally decoupling the dosing element from the dose selector during dose dispensing. The clutch includes a male spline, a corresponding female spline and a curved or inclined surface which is orientated such that re-engagement of the clutch guides the male spline into a predefined rotational orientation with respect to the female spline.
