A positioning device suitable for accurately positioning objects such as optical fibers includes a first support, a movable support restrained for movement relative to the first support with one degree of freedom and carrying a holder for the object to be positioned, and an intermediate support which is connected to the first support by a pair of first spaced flexible elements of equal length and which is connected to the movable support by a pair of second spaced flexible elements, the second pair also being equal in length to each other. The first and second flexible elements are oppositely arranged and dimensioned so that arc-errors in the movement of the intermediate support caused by bending of the first flexible elements are substantially compensated by arc movements of the second flexible elements to produce a desired movement of the movable support, which may be rectilinear or angular movement about an axis. An actuator causes movement of the movable support with bending of all the flexible elements, and a control member connects the first support, the intermediate support and the movable support so that the degree of movement of the intermediate support is one half the movement of the movable support.
