Then the "gear" from this insect would also not count as it does not transfer motion. Its more like a joint that has teeth for extra grip.

> an intricate gearing system that locks their back legs together, allowing both appendages to rotate at the exact same instant

That sounds like transmission of motion to me?

If I lock my hands together, rotating one of my wrists also rotates the other wrist. I'm not saying it's a _useful_ transfer of motion though!

Only if one leg is pushing the other leg

> To confirm that the gears performed this function, the researchers performed a neat (albeit morbid) trick with some dead Issus. They manually cocked their legs back in a jumping position, then electrically stimulated the main jumping muscle in one leg so that the leg extended. Because it was rotationally locked by the gears, the other non-stimulated leg moved as well, and the dead insect jumped forward.
