1. A wearable drug delivery device comprising:
an outer housing;
a drug storage container positioned at least partially within the outer housing; and
an insertion mechanism positioned at least partially within the outer housing and including:
an insertion mechanism housing,
a rotational biasing member configured to rotate at least a portion of the insertion mechanism housing about an axis, wherein at least a portion of the rotational biasing member extends around the axis to form two or more revolutions around the axis and the at least a portion of the insertion mechanism housing,
a delivery member moveable between a first position wherein an insertion portion of the delivery member is positioned within the outer housing and a second position wherein the insertion portion of the delivery member is positioned exterior to the outer housing for insertion into a patient, and
a hub configured to:
(i) facilitate a connection between the delivery member and the drug storage container such that a fluid flow path passes through at least a portion of the hub during operation of the wearable drug delivery device, and
(ii) mechanically engage with the insertion mechanism housing such that initial rotation of the insertion mechanism housing with respect to the hub causes the delivery member to move along or parallel to the axis from the first position to the second position.
