The cover has a shaft bore that receives the shaft of the shaft-plate assembly.

Each one-way driver drives the drive stem into the cartridge through a drive surface to provide a range of dose selections.

The shaft defines a shaft axis.

The combination headless drive shaft-hang shaft also includes a drive shaft connected to the hang shaft and the drive shaft includes a drive element in the drive shaft.

The selection can be made by a pin inserted through an aligned hole between a link and the rod.

The shaft includes a plurality of shaft ports distributed around a circumference of the shaft.

The shaft system has a proximal shaft section and a distal shaft section.
