The link you provided does not indicate the Oldham style is zero

backlash is the curved jaw GS series.

You're right, it doesn't say so specifically, but the page also
neglects to specify that the bellows coupling is zero backlash.

Here's Huco's description:

"Rotation is transmitted through a central disc that slides over the
tenons on the hubs under controlled preload conditions to eliminate
backlash."

It will be far easier to limit and undo the follies of an

and good judgment to a depraved electorate willing to have
such a man for their? president.. Blaming the prince of the

fools that made him their prince".
