Here's another interesting automotive techie gem.

How do they couple it to the drive line?

How about attaching magnets around the outside and having it spin
inside coils to make a self-contained engine+alternator?

FWIW, it looks to me like this engine violates a basic point of IC
engine design for thermal efficiency. By using a separate combustion
chamber, it multiplies the surface area relative to the volume of
combusted gas. The result is a very high ratio of lost heat to useful
heat.

This is what kills the efficiency of flathead engines. This one looks
worse in that regard.
