Is the square, coincidentally, the same size square as a winch handle 'square' which are a standard size (of 11/16th" ?? - not sure that is correct)

fine rat tailed file?

I'd say the square 1½ in. X 1½ in. (38 mm X 38 mm)
I'm quite sure you would get enough leverage with a winch handle onto the rudder stock.

This yacht has a similar emergency steering system to the one I am planning but since my yacht is center-cockpit I'll have to bring the rudder stock extension up through the aft cabin roof and then ropes forward to the sheet (halyard?) winches

So why not just use steel wire rope?

So why not just use steel wire rope?

Too simple?
A well set up wire system seems to usually be as good as anything.
I guess the aim is to minimise backlash, which is irritating when sailing down waves.

In industrial stuff, people might use a length of timing belt to solve similar problems.

if you have fraying that is either misalignment of the rope path with a sheave which causes rubbing on the sharper sheave edge. Or the Sheave is burred. I ve aseen a lot of boats with lousy steering sheave alignment, It doesn't do wire systems any good either.
