Does a CVT have clutches?

Question

I read somewhere that:
"A CVT doesn't have gears or a clutch. Instead, intelligent electronic controls, typically working in tandem with a torque converter, choose from an infinite number of gear ratios within a given ratio “spread,” which usually also is broader than the ratio spread available in conventional automatic transmissions. The CVT's absence of fixed gear ratios allows it to keep the engine operating at its optimum power/torque ranges in relation to the driver's load demand".
