603121 A system for a drug delivery device includes a reservoir holder 380 configured to hold a reservoir, and an alignment interface 350 comprising a main body 352 configured to be coupled to the needle receiving end of the reservoir 20. A first alignment feature 372 is provided on the main body 352 which cooperates with a corresponding alignment feature such as a sloping ramp 388 provided by the reservoir holder 380 such that when the interface that caps the reservoir is inserted into the holder 380, the first alignment feature 372 cooperates with the corresponding alignment feature 388 provided by the holder 380 so as to rotate the alignment interface 350 and thereby align the alignment interface 350 within the holder 380. The system further includes one or more coding features, constituted by the alignment feature such as protrusion 372 itself or other physical protrusions 374, 376, which allow the alignment interface to be mechanically coded to an inner wall of the reservoir holder. |
