I wonder if it would be worth trying disabling the chain closer and fitting
an over-door closer - the sort with separate adjusters for close and latch
speeds. They might have rather more sophistication than simply slamming
shut.

The mechanism will probably have to go on the outside of the door, as it's
probably intended to keep the stairwell clear of smoke in the event of a
fire in the flat.
