<p>An assembly for a drug delivery device comprises a first drive member for driving a piston rod, wherein in a first state of the assembly the first drive member is moveable with respect to a second drive member and the piston rod is configured to be moved with respect to the first drive member when the first drive member is moved with respect to the second drive member. The assembly further comprises a coupling member being configured to couple the first drive member with the second drive member in a second state of the assembly, so that the movement of the first drive member with respect to the second drive member is prevented, thereby forming a drive unit for a set and delivery action of the drug delivery device.</p> |
