What's the opposite of a lead screw?

A lead screw is very efficient at pushing a nut when it turns. However, if you push on the nut it's not very good at turning the screw. I need the opposite of that: Something where if I push the nut, it's really efficient at turning the screw. What are some examples of things like that which I could buy? One example would be a "yankee" or spiral screwdriver. I'm particularly hoping for things with shaft sizes between 2mm and 6mm (5/64" to 1/4"). Thanks!
