It was already known that civilian side deals would be prioritised in this visit. Indo-Russia military relationship has been always strong.
On the military side the most prominent pact that was signed was RELOS.
The pact permits up to five warships, ten aircraft, and 3,000 military personnel from either country to be stationed simultaneously in the partner nation's territory for five years, with a provision for a further five-year extension upon mutual consent. The details were confirmed by First Deputy Chairman of the Russian State Duma's International Affairs Committee Vyacheslav Nikonov following the Russian Parliament's ratification.
In the space domain Russia has offered 100% Tot for RD-191M cryogenic engine. This will be a decent improvement over India's current Indo-French Vikas engine.
Additional S400 units, buying R37M missiles and the modernisation of the Super Sukhoi is already ongoing.
And they've pitched engine transfer (PDA 14) for India's MTA (competing against Embraer C390, C130J and Airbus A400M)
Su57 and S500 are under consideration. They were no indications of signing a final deal. S500 is something that even Russia has only one regiment of.
So it's not a nothinburger as you're suggesting.
