Example transmissions for rotating coaxial drive shafts in opposite directions are described herein. An example apparatus includes a first face gear coupled to a first drive shaft, a first elliptically interfacing gear coupled to a second drive shaft and facing toward the first face gear, the second drive shaft disposed within and coaxially aligned with the first drive shaft, and a wobble plate disposed between the first face gear and the first elliptically interfacing gear. The wobble plate has a second face gear on a first side of the wobble plate engaged with the first face gear and a second elliptically interfacing gear on a second side of the wobble plate engaged with the first elliptically interfacing gear. The wobble plate is to rotate the first face gear and the first elliptically interfacing gear in opposite directions.
