An assembly for a drug delivery device is provided, the assembly having a compression spring, wherein the compression spring is compressed during the setting of a dose of a drug. The assembly further comprises a sleeve member, wherein the compression spring is in direct contact with the sleeve member and wherein the compression spring and the sleeve member are configured such that a relaxation of the compression spring effects a rotational and an axial movement of the sleeve member in a proximal direction, thereby causing a dispensing of a dose from the drug delivery device.
