An assembly for a drug delivery device comprises a housing having a proximal end and a distal end, a dose button configured to be moved with respect to the housing for setting and delivering a dose of a drug, and a resilient setting member. For a dose delivery movement, the dose button is arranged to be moveable in the distal direction with respect to the housing from a dose delivery position, thereby deforming the resilient setting member to store energy in the resilient setting member. The assembly is configured to use the energy stored in the resilient setting member for a dose setting movement to move the dose button in the proximal direction with respect to the housing into the dose delivery position. Furthermore, a drug delivery device is provided.
