An angle grinder key does it for me.

Apologies, please bear with me.
I do not have an angle grinder, so other options would be good to see.
However, if I did use an agle grinder key, do I just turn the piston and it moves in an out of the caliper? DO I need to apply pressure?
What I cannot understand,is that if the piston turns in and out of the caliper, how does the pad stay in the in notch?

Just had the same requirement myself and bought one of these on eBay after deciding it was worth having one for the future....

Made by Laser and about £15 off ebay or £24 from halfords. Works perfectly and takes seconds to do.
I wondered about the pad/notch - I'm guessing theres a pawl inside that allows the autoadjuster to rotate one way while the piston stays put
then the action of winding it back engages the pawl so the piston drives the autoadjustment part.
(could be talking aout my arse though)

Thats correct. Its like a screw type thing.

You need to apply pressure to it while winding it back in otherwise it goes nowhere. A clamp setup is ideal.

I have the caliper wind back tool.
For ones where the piston needs to turn, you turn the central threaded part and the pistons rotates as it retracts.
For one where you just want to push it back in, you turn the collar instead and the piston retracts but does not rotate.
Easy peasy.
Or, a big set of plumber's grips works for just pushing them back.
For windy back calipers, the proper tool is worth a few quid of anybody's money and acquiring tools is what we're all about, is it not ?
