Abstract

An assembly for a drug delivery device and an associated drug delivery device are provided. The device has a drug delivery device housing and a medicament contained in the drug delivery device housing. A clutch is established between the dose knob and the dial link to prevent inadvertent proximal axial movement of the lead screw away from the cartridge piston, which can lead to dosing inaccuracies.
