Any tube style belay device would work for rappelling and all would twist the rope less than a figure eight device.
For belaying from above, the Munter Hitch directly on the anchor is an accepted method. Another method is to use one of the belay devices in the "autoblocking" mode, such as the B-52, reverso, GiGi or the ATC-Guide.
Yet another method is to belay off your harness using a belay device in the standard mode with a "redirect" to the anchor.
