  • Patent number: 9737666
    Abstract: An assembly for a drug delivery device is disclosed. An example assembly includes a housing, a rotation member, a drive member, and at least one correction member. The rotation member is adapted to be rotated with respect to the housing in a first rotational direction for delivering a dose of a drug. The drive member is coupleable to the rotation member for delivering the dose. In a delivery mode, the drive member and the rotation member are coupled such that the drive member follows rotational movement of the rotation member in the first rotational direction due to mechanical interaction of the rotation member and the drive member. In a correction mode, the rotation member and the drive member are decoupled such that the rotation member is rotatable in the first rotational direction with respect to the drive member.
