I always thought that a fluid flywheel and a torque convertor were one and
the same.

Torque converter has an extra vaned bit in the middle over a fluid flywheel-
the stator. See http://en.wikipedia.org/wiki/Fluid_coupling

The howstuffworks article on torque converters is better than usual - it's
actually useful, rather than just a paraphrase of a marketing leaflet.
