While some were predicting for a long intervention, Russian military bases and Tokayev handing the keys of Nur-Sultan to a Russian general, none of that happened because Russia acted very thoughtfully towards its ally. Russia's broad support to Kazakhstan in a difficult moment, which allowed Kazakh govenment to restore order. This support was pragmatic and professionaly executed to achieve immediate results.
Russia's interest is to keep Kazakhstan stable with a strong president who is not accused of depending on foreign interference. The same could have happened in Belarus, but Alexander Lukashenko was overconfident and missed the right moment before Western “colour revolution” techniques were used in domestic protests.
