A robotic arm having at least pair of structural members rotatably coupled to one another, with a first one of the structural members defining a central passage. A communications link is at least partially within the robotic arm for signal transmission between within the robotic arm. The communications link includes a signal transmission device having a coiled portion, with ends of the coiled portion adapted to be connected to parts of the communications link, whereby the coiled portion is a segment of the communications link. The coiled portion has one of its ends connected to the second one of the structural members to rotate with the second one of the structural members, the other of the ends of the coiled portion connected to a component associated with the first one of the structural members through the central passage to rotate with the first one of the structural members, at least a portion of the coiled portion expanding or contracting radially during relative rotation between the pair of structural members.
