A cannula insertion device for use with an insertion set includes an insertion module and a cannula insertion needle. The insertion module includes a housing with a distal end, a proximal end, and a torsion bar integrated into the proximal end. The cannula insertion needle is attached to the torsion bar. Moreover, the torsion bar is configured to releasably retain a cannula cartridge and an infuser base of the infusion set in operative alignment with the cannula insertion needle. The torsion bar is also moveable from a retracted position, wherein a cannula cartridge and an infuser base are releasably retained on the torsion bar and are completely within the housing opening, and an advanced position wherein a cannula of a cannula cartridge has been subcutaneously inserted into an infusion site by the cannula insertion needle.
