1. A modular administration device configured to be affixed to skin of a user, comprising
a reservoir module comprising a reservoir, a reservoir module housing, a first connecting structure, and a first electrical contact arrangement, wherein the reservoir defines a first axis; and
a pump module comprising a piston rod, a pump module housing, a second connecting structure disposed around the piston rod, and a second electrical contact arrangement, wherein the piston rod defines a second axis,
wherein the first electrical contact arrangement is generally perpendicular to the first axis and the second electrical contact arrangement is generally perpendicular to the second axis,
wherein the reservoir module and the pump module are releasably connectable via the first and the second connecting structures such that upon establishing a releasable connection, the piston rod is configured to cause a fluid medicament to be dispensed from the reservoir by a movement of the piston rod,
wherein, to connect the reservoir module and the pump module,
in a first step, the first and the second connecting structures are plugged together such that the first and second axes come to coincide and form a common axis of rotation, and
in a second step, the pump module housing is rotated relative to the reservoir module housing about the common axis of rotation and the first electrical contact arrangement becomes electrically connected to the second electrical contact arrangement through such rotation,
wherein the first electrical contact arrangement is positioned farther from the first axis in a radial direction than the first connecting structure, and the second electrical contact arrangement is positioned farther from the second axis in a radial direction than the second connecting structure.
