I realise now that my answer was completely off.
And you meant to ask about the lifter only...
It was late at night, I read fast, and guess I did not pay full attention...
So this is the way I do it:
After screwing in the threaded body of the lifter into the tappet box
With the lifter spindle already inside it,
And positioning the peg at the correct place,
I insert the spring, positioning the lifter arm,
(As Ron mentioned, the peg and lever have fine splines) and start fastening the nut.
At that stage I just hold the lever, as the splines are already engaged,
And continue fastening the nut...

Noam.
No worries! My explanation wasn't exactly the best .
I'll pull the assembly out to check but I suspect the reason for my trouble is that the splines are worn to the point the lever arm is allowed to spin freely on the shaft. I was able to tighten the arm such that it can lift the valve without rotating, but I'm hesitant in putting faith in it staying that way.
If I need a replacement lifter arm assembly, where should I look to source one?
