1. An injection device comprising:
a piston rod for ejecting a dose of medicament from the injection device, the piston rod being arranged along a first longitudinal axis;
a housing having a second longitudinal axis, wherein the first longitudinal axis is substantially parallel to and offset from the second longitudinal axis;
a drive assembly including a first driver component part arranged concentrically about the second longitudinal axis, the drive assembly capable of providing a force to the piston rod for ejecting the dose of medicament from the injection device;
a power reservoir, wherein the drive assembly is rotationally drivable by the power reservoir, the power reservoir comprising a torsion spring configured to be loaded by a user to set the dose of medicament to be ejected by retaining a rotational force, the torsion spring configured to be released to impart the rotational force to the drive assembly to rotationally drive the drive assembly; and
a dose setting element operable by a user to load the torsion spring.
