A centraliser comprises arm assemblies pivotally connected between first and second support members. Each arm assembly comprises a first arm and a first pivot joint having a first pivot axis, a second arm and a second pivot joint having a second pivot axis, the first and second arms pivotally attached together via a third pivot joint having a third pivot axis. The arm assemblies are arranged in diametrically opposed pairs. In some embodiments the first arm comprises a fork section to position the first pivot axis coincident with the central longitudinal axis of the device, or so that the first pivot axis and the third pivot axis are positioned on opposite sides of a plane coincident with the central longitudinal axis of the device.
