I am not sure what the standard name for this fixing is now. I guess we could give it an international standard via homemadetools. Any ideas please post (funnier the better)

Hi All
This post via Wikipedia explains all about different types of keys:
https://en.wikipedia.org/wiki/Key_(engineering)
I also saw this on the web:Dutch Pins: How To? - Page 3
So it appears they are both correct. You never stop learning!A "Scotch key" or "Dutch key" also provides a keyway not by milling but by drilling axially into the part and the shaft, so that a round key can be used. If the key is tapered, it is referred to as a "Dutch pin" and is driven in, and generally cut off flush with the end of the shaft. A Hirth joint is similar to a Spline joint but with the teeth on the butt of the shaft instead of on the surface.
Now I'm curious. I can see "scotch key" meaning "cheap-ass key" but I'm wondering where "dutch" comes from.

I believe 'dutch' might mean practical but workmanlike, alternative method. Once, I had double-hung window sills to replace that had decayed. Upper surface was OK, underside was splintered and ragged. A carpenter told me, make a "dutchman". Unstable pine wood was pared down to solid material by 4" power-saw, chisel and bullnose plane. Then replaced with poplar, then contours were shaped and painted like original. A little tedious working upside down, back in 1981. They are still in place, indistinguishable from original.
I'm not Scottish, but know a few...they are not the stereotypical cheap, they just get a lot of bang for the buck. And unlike some cultures, their products are first rate. True cheapskates don't do that!
Sincerely,
