Крутить is from the Proto-Slavic root *krǫt-, Old Church Slavonic крѫтити. In this word and in its cognates in other Indo-European languages, as Vasmer has it, we see the nasal element in the root. The Proto-Slavic nasal vowels developed from a combination vowel + nasal consonant when the Proto-Slavic law of the open syllables began to work and all the closed syllables got opened.
Корчить is from корчи 'spasms', which is from the Proto-Slavic *kr̩čь < PIE *(s)ker 'to turn (крутить), to bend (гнуть)', related to the Latin curvus 'bent, curved' (изогнутый) and Greek κυρτός (kyrtós) with the same meaning. Here we see no nasal element in the root, so the etymological connection of корчить and крутить is dubious, although semantically they are prety close. On the other hand, короткий (from the same PIE root *(s)ker) is related to корчить, but surely not to крутить.
The original nasal consonant in the root of крутить makes it unrelated to the other two words.
