Assembly for a drug delivery device and drug delivery device An assembly for a drug delivery device (1) is described comprising an activation member (6A) adapted and arranged to be axially moved in a delivery direction for triggering a dose delivery operation of the assembly, a first interaction member (17) and a second interaction member (18) which are adapted and arranged to mechanically cooperate with one another during a dose delivery operation of the assembly and to be rotated with respect to one another during the dose delivery operation, wherein the assembly is configured such that movement of the activation member (6A) in the delivery direction brings the interaction members (17, 18) into mechanical contact for generating a friction between the interaction members (17, 18), wherein an amount of friction controls a relative rotational speed of the interaction members (17, 18) during a dose delivery operation. Furthermore, a drug delivery device comprising the assembly is described.
