1. A drive mechanism for a fluid delivery device, comprising:
a plunger disposed within a reservoir;
a leadscrew extending from the plunger;
a nut threadably engaged with the leadscrew;
a drive wheel; and
a clutch mechanism coupled to the drive wheel, wherein the clutch mechanism is configured to allow the nut to pass through the clutch mechanism when disengaged and is configured to grip the nut when engaged such that the drive wheel rotates the nut to advance the leadscrew and the plunger into the reservoir.
