Surely that one will fit once you remove the old brass valve and its arm?
you could probably put the handle in the hole in the other side of the cistern front, but you would have to take the cistern off to rotate the syphon.
It would be easier to fit a different fill valve.
the Fluidmaster is a good one

You can still get the Torbeck or copies, but they can clog if there is sediment or limescale in the water. Yours looks pretty clean.
