One way to accomplish this (especially simple if you are using a 1/2" Hex shaft in your mechanism is to just slip a 1/2" ratcheting box-end wrench on the shaft somewhere. This prevents back-driving. Another option is to use a worm gearbox somewhere in the mix which also tends to prevent back-driving.
